There are many ways to sharpen your mind, and here are a few quick ideas to get you started:

Exercise – The physical exercises will sharpen your mind. It helps with the mental clarity, concentration and focus. Look at YouTube videos to learn how to do yoga or pilates from home. Make sure you always check with a doctor if you are unsure.
Meditation – It helps with the developing a more positive outlook on life and see things from a different perspective. It will give you peaceful time to think about things, in a relaxed environment.
Reading – Reading is one of the best ways to sharpen your mind because it can expose you to new ideas, broaden your vocabulary and increase mastery of complex content. This can be any genre – it doesn’t have to be a high brow book at all. Romantic fiction is an easy read, but still teaches you a lot.
Online games. Learning a more complicated game like Solitaire will provide you with some real brain exercise. Try out this great version called Freecell – the website also provides you with some great history of the games, as well as how to play it. You can really get sucked in to learning more and more variations of the game.

Test your own skills – this Zero-21 game absolutely baffled me for days, but then when the penny finally dropped, I was addicted! It’s also a great way to have fun online without causing yourself extra stress from news sites or group chat dramas.

Learning a new skill – Learning a new skill will increase brain health through creativity, socialisation and self-expression. New skills can also help improve working memory capacity, critical thinking skills and problem solving skills.
